Yes.. there was a bit of swearing involved.
I also made the mistake of fitting the truss rod cover before fitting the nut. As a result it is about 1/2mm off kilter. I'm also not happy with the seating & height of the nut.. I think I'll be pulling the nut off, plugging the drill & truss rod holes, & reworking the face of the headstock.
I've strung it up as is & I'm also not happy with the pickup position. It is a few mm north of where it should be. I might try repositioning it.
On a positive note, I've wired it up & it is sounding great. I'm also really happy with the finish that the Stock Sheen Conditioner has given it. It is so smooth.
